I recently installed my new msi Geforce GTX 1080 into my computer and when I tried to turn it on to see if it works, the computer is turn on, all the leds lights and the fans in the case works normally but the fans and the led light on the graphic card didn't work and the monitor is still in save mode.
When I took it apart and removed my graphics card and installed the old one the computer started up again normally. So I'm confused whether it's my power supply not being able to handle my graphics card or my new graphic card is damaged ?

What display are you using and how is it connected?

The power supply you have has two 6+2-pin PCIE power cables. Your graphics card likely has two PCIE power connectors so you will need to connect both from the power supply.
